NCT03632356

Brief Summary

Using a randomized controlled trial (RCT) design, the main objective of this study is to evaluate the clinical, patient-centered, and economic effectiveness of a stepped-care intervention for patients with panic attacks and panic disorder presenting to the busiest Accident and Emergency (A\&E) departments of the largest public healthcare group in Singapore. The RCT will have two arms: 1) treatment via an enhanced care pathway consisting of a stepped-care intervention for panic attacks and panic disorder; and 2) a control arm consisting of screening for panic attacks and panic disorder in the A\&E and discharge (routine care). In addition to the baseline assessment, the study follow-up visits will occur at 1, 3, 6, and 12 months.

Outcome Measures

Primary Outcomes (1)

  • Change in panic scores at every 3 months from baseline using the Panic Disorder Severity Scale (PDSS; Shear et al., 2001)

    The PDSS is a 7-item semi-structured interview of panic symptom severity. Each item is rated on a 0 (none/mild) to 4 (extreme/severe) scale. A higher total score would represent severe panic symptoms.

    Baseline, 1st month, 3rd month, 6th month, 12th month

Secondary Outcomes (4)

  • Short Form Health Survey (SF-36; Ware & Sherbourne, 1992)

    Baseline, 1st month, 3rd month, 6th month, 12th month

  • WHO Disability Assessment Schedule (WHO-DAS; World Health Organization, 2010)

    Baseline, 1st month, 3rd month, 6th month, 12th month

  • Psychiatric Diagnostic Screening Questionnaire (PDSQ; Zimmerman & Mattia, 2001)

    Baseline, 1st month, 3rd month, 6th month, 12th month

  • EQ-5D (EuroQol Group, 1990)

    Baseline, 1st month, 3rd month, 6th month, 12th month

Other Outcomes (2)

  • Clinician Global Impression Severity Scale (CGI; Guy, 2008)

    Baseline, 1st month, 3rd month, 6th month, 12th month

  • Panic Disorder Module of the Structured Clinical Interview for DSM-5 (SCID; First et al., 2015)

    Baseline, 1st month, 3rd month, 6th month, 12th month

Study Arms (2)

Stepped Care Intervention (STEP)

EXPERIMENTAL

In a stepped-care model, all patients start with an evidence-based intervention of low intensity as a first treatment step. Progress is monitored and patients who do not respond adequately can subsequently be 'stepped up' to a higher intensity treatment. This model is now being recommended as the best strategy for treating panic attacks and panic disorder.

Behavioral: Stepped Care Intervention (STEP)

Screening only

ACTIVE COMPARATOR

Screening only for panic attacks and panic disorder using a gold standard clinical interview that provides coverage of the core symptoms of panic attacks and panic disorder.

Diagnostic Test: Screening only

Interventions

A stepwise progression of intervention according to the participant's response to the increasing levels of therapy. There will be 1 session of psychoeducation, followed by 5 sessions of Cognitive Behavioral Therapy (CBT) if panic symptoms do not improve at 1-month follow-up.
